I have a funny feeling that if you tried to order a dale part from them, they would not have any. Notice the bottom of their page it says 'Copyright ???? 2002 Pro-Tect Fabrications. All rights reserved.' I think what you have here is someone that doesn't update their web pages very often. Or I could be wrong.
The grab bar is different, a lot like a PRM brand bar. The only thing I don't like about it is those flat pieces hurt your hands when you grab them... Then again if you have to grab in that location you must be really stuck, in which case you deserve some pain anyway...
Spoke with Dan the owner today... They have all the Dale parts in stock..... Belly pan is cheaper than the rear because fabrication is MUCH simpler. Sounds like a standup guy with a high regard for quality.
